Boy band
98 Degrees reunited for the first time in 10 years on
"Today" Friday (Aug. 17), where they performed their hits "Because of You," "I Do" and "Hardest Thing." But the stars say they've definitely graduated from "boy band" to "man band" (which just sounds weird to us, but we understand what they mean). They also say it is like riding a bike, though it's a bit harder now.

"It's great to be back together and do what we love to do together on stage," says
Nick Lachey. But his younger brother
Drew quips, "There's back pain, throat pain, knee pain, ankle pain, hip pain. Our menu went from like steak and lobster to Metamucil and prune juice."

The group is not reuniting for "Today." They will also be performing this weekend at the MixTape Festival in Hershey, PA, alongside Aaron Carter, The Fray, New Kids on the Block, Backstreet Boys, Kelly Clarkson and Carly Rae Jepsen. Should be a fun time!
